Researchers at Osaka University developed a nanostructured light diffuser that provides balanced lighting by diffracting blue and red light, and can be cleaned by simple rinsing with water. The diffuser consists of cheap materials and can be shaped with common tools. A protective glass coating maintains the diffuser’s optical performance yet adds durability. This work might improve the visual performance of everyday lighting displays.

To extend the depth of field in mask-based lensless cameras, researchers from Osaka University replaced conventionally coded masks with a radial-coded mask optimized to balance the frequency response. As a result, the point spread function depends less on distance, and subjects at various depths can be clearly imaged. Experiments in simulation and on a prototype show that the depth of field of the camera is extended when the proposed radial mask is used.

Researchers from Osaka University have developed a data-driven AI algorithm for controlling the heating and cooling of an office building. The system does not require ambient sensors or specific knowledge of the building’s rooms. During heating operations, the system was able to achieve energy savings of up to 30%, which can represent significant reductions to cost and environmental impact.

Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).

The annual burning of crop residue in India causes widespread air pollution, particularly in the northwestern regions. A group of international researchers has used low-cost yet reliable instruments to gauge the effects of air pollution in these areas, making it the first quantitative study of its kind.

A recent discovery in spintronics could potentially transform future electronics. A group of researchers have revealed the key role of cobalt-tin-sulfur in reducing energy consumption, unlocking new possibilities for high-speed, low-power spintronic devices.

Scientists have revealed that the outer part of our brain (the cortex) is skilled at managing all the info it gets from the outside world thanks to special groups of nerve connections called modules, which work together but also independently.

The physical laws of everyday water flow were established two centuries ago. However, scientists today struggle to simulate disrupted water flow virtually, e.g., when a hand or object alters its flow. A research team from Tohoku University has harnessed the power of deep reinforcement learning to replicate the flow of water when disturbed. The replication allowed for recreating water flow in real time based on only a small amount of data, opening up the possibility for virtual reality interactions involving water.

Researchers have explored the efficacy of combining solar panels on rooftops with electric vehicles acting as storage batteries in Paris and its surrounding areas, finding some encouraging results.

To address the lack of suitable training data for deep-learning semantic segmentation models in urban landscaping, researchers from Osaka University developed a method that generates a training dataset without the need for real images or a model of an existing city. The method, which is based on procedural modelling and image-to-image techniques, enables segmentation models to achieve comparable performance under some conditions at a fraction of the cost of real dataset generation.

Systematic copper doping boosts all-solar utilization in tungstic acid nanocrystals.

A research team led by researchers from Osaka University created an aluminum-nitride device that can convert visible light into deep-ultraviolet light through the process of second harmonic generation. This work can lead to the development of practical devices that can sterilize surfaces with ultraviolet radiation while using less energy.

In this collaborative project between Newcastle University and Universiti Malaysia Perlis (UniMAP), the team aimed to create a sustainable, cost-effective lower limb prosthetic socket (LLPS) using natural fiber-reinforced composites. The objectives included designing a green LLPS, assessing its environmental impact, and engaging stakeholders. PALF was selected as a sustainable reinforcement and incorporated into the composite. The design was guided by a static-friction (‘stiction’) load-transfer framework, developed previously by Goh and co-workers, which explains how force is transferred from the polymer to the fibres. The project has also inspired worldwide interest in sustainable LLPS development through a press release, receiving inquiries from students at Nanyang Technological University in Singapore and a group of 7th graders in the USA.

Solid-state batteries are a safer option that can hold even more energy than current go-to lithium-ion versions, but effectively harnessing their structure-performance relationship has remained a complex barrier to better batteries. Now, however, researchers at Tohoku University’s Advanced Institute for Materials Research in Japan have developed a framework to predict how the structure of solid-state electrolytes can affect the performance of a battery.
